Tunnel length: infobox says 50.46 km, narrative says 50.5 km

The article states two slightly different lengths for the Channel Tunnel, with no explanation for the discrepancy.

Infobox (line length field): "50.46 km"

Narrative section: "Between the portals at Beussingue and Castle Hill, the tunnel is 50.5 km long."

The two figures — 50.46 km and 50.5 km — differ by 40 metres. While this sounds small, both are presented as precise factual measurements (not ranges or approximations), and 50.46 does not round to 50.5 by standard conventions (it rounds to 50.5 only if truncating to one decimal place, but the infobox quotes two decimal places, implying higher precision). The two sections likely cite different sources or measure slightly different terminal points, but the article does not say so.

For a structure whose exact length is well-documented by its operators (Eurotunnel), the article should resolve this to a single consistent figure with a citation, or explain what each measurement endpoint refers to. Rome (talk) 17:50, 5 May 2026 (UTC)
